[Comparison between pressure controlled and controlled mandatory ventilation in the treatment of postoperative hypoxemia after myocardial revascularization].

Background And Objectives: Pressure controlled ventilation (PCV) has been used as the ventilation mode of choice in coronary artery bypass graft surgery patients who develop severe hypoxemia in the immediate postoperative period. However, there are no evidences showing that pressure controlled ventilation is more effective in reversing postoperative hypoxemia than controlled mandatory ventilation (CMV). This study aimed at comparing the effects of both ventilation modes on systemic oxygenation in cardiac surgery patients who develop hypoxemia characterized by PaO2/FiO2 ratio lower than 200 in the immediate postoperative period.

Anterior cruciate ligament ganglion: case report.

Context: A ganglion is a cystic formation close to joints or tendinous sheaths, frequently found in the wrist, foot or knee. Intra-articular ganglia of the knee are rare, and most of them are located in the anterior cruciate ligament. The clinical picture for these ganglia comprises pain and movement restrictions in the knee, causing significant impairment to the patient.
